Abstract
A vacuum cleaner includes an odor neutralizer and dust plume abatement system. The odor neutralizer and dust plume abatement system delivers a mist to a working air path of the vacuum cleaner, such as at or upstream of a working air treatment assembly defining a portion of the working air path.
Claims20
A surface cleaning apparatus, comprising:
- a housing;
- a working air path through the housing comprising a dirty air inlet and a clean air outlet;
- a working air treatment assembly defining a portion of the working air path, the working air treatment assembly comprising:
- a cyclone separator,
- a dirt cup configured to receive and collect contaminants separated by the cyclone separator, the dirt cup further comprising an aerosol inlet, and
- a displaceable seal provided at the aerosol inlet on the dirt cup with the displaceable seal in a normally closed position, wherein the displaceable seal is adapted to open at a predetermined pressure, and
- a suction source defining a portion of the working air path and in fluid communication with the working air treatment assembly;
- and
- an odor neutralizer and dust plume abatement system configured to dispense a mist into the working air path and including a receiver including a mount for receiving an aerosol dispenser, the receiver in fluid communication with the working air path at or upstream of the working air treatment assembly via the aerosol inlet.
